Transfer of Curved Members

Imported curved segments will be GENSECs and new straight segments will also be GENSECs. However, if merging with an existing model and the interface can identify the source member that was originally a SCTN, it will remain a SCTN.

Comparing GENSECs is only down to the point count level on the spine. The actual point attributes are not investigated, except for the start and end points. If there are the same numbers of POINSP and CURVE members respectively these are checked. Any alteration to these numbers will indicate changes. They must be inspected visually for comparisons. The re-imported CURVE element are likely to have changed because we only import 1 type - a THRU point, although there are 6 or 7 different types of CURVE points in the base product, each with different attribute combinations.
